Resumé

Eradication of Aleutian disease was initiated in Denmark in 1976. The prevalence of positive farms has since then been reduced from 100% to only being continuously present in the region of Vendsyssel, Northern Denmark since 2004. In this study, we attempted to identify risk factors for the infection in this region based on logistic regression of spatial (environmental, neighbourhood) variables and biosecurity measures. Information on potential biosecurity (management) risk factors in the region was obtained from interviews in 342 registered farms in the region using a structured questionnaire. A total of 279 questionnaires were completed (response rate 82%). Additional spatial variables were included in the analysis. The study shows that farm size (the number of animals in the farm) and proportion of infected neighbouring farms were significant risk factors for infection with Aleutian Mink Disease Virus. These factors account for 35% of the variation of the infection status of mink farms located in Vendsyssel during 2009. These results indicate that only a coordinated effort from the farmers in the area will succeed in eradicating the disease from Denmark, because individual farms that have eradicated the disease will be at risk of re-infection from test-positive neighbours.

N2 - Eradication of Aleutian disease was initiated in Denmark in 1976. The prevalence of positive farms has since then been reduced from 100% to only being continuously present in the region of Vendsyssel, Northern Denmark since 2004. In this study, we attempted to identify risk factors for the infection in this region based on logistic regression of spatial (environmental, neighbourhood) variables and biosecurity measures. Information on potential biosecurity (management) risk factors in the region was obtained from interviews in 342 registered farms in the region using a structured questionnaire.
